Alternatively, you can just wear the T-shirt and be yourself. Though you won't be unique. The 'S logo, unmistakeably connected to the do-gooder dude in trunks and tights, was a favourite T-shirt in the Seventies. And, now, as with almost everything else that was hip then, it has been rediscovered and recycled.
Since the T-shirts first hit the shelves two months ago, HMV have been selling 1,000 a month, mainly to Superman fanatics and young (those not alive when the first time these T-shirts were trendy) clubbers. Up, up and away and all that.
Superman T-shirts cost pounds 9.99 from HMV shops.
